The vapour emitted from e-cigarettes has been linked to a baby’s learning skills later in life and a baby’s co-ordination and memory development.

In the same way links have been made to babies exposed in the womb to smoking tobacco and a heightened risk of learning difficulties or attention deficit hyperactivity disorder, the effect of the vapour from e-cigarettes is said to have the same effect.

The new study was carried out by Professor Judith Zelikoff from New York University’s department of environmental science. Professor Zelikoff has spoken out about her findings and warned women who turn to e-cigarettes during pregnancy in the belief it is a safer option, need to be aware this is not the case.
